Abstract
Recently, accidents have occurred in waste disposal and recycling facilities. This has led to requests to construct a safety and security system in those facilities. I propose the use of the safety design technique known as SAD (Safety design Analysis with Database) as a new risk assessment technique. We define the risk as the amount of damage. We made the formula of the amount of damage which is composed of the amount of the personal damage and the facilities damage, and the facilities stop damage. We carry out an assessment of the safety level by using SAD. SAD is a technique which combines quantity risk assessment features from both top-down systems such as FTA and bottom-up systems such as FMEA, in conjunction with the information provided by accident, trouble and HIYARIHATTO databases. This paper presents an outline of SAD, as applied to the meltdown & power generation facilities. By adding information on facilities to ATHDB, SAD could quantitatively assess the risk of 137 accident cases. In addition, using the ATM (Accident Tracing Map), each accident case could be clearly described and the safety improvement plan examined.
